A mountain so high that its summit is unknown, completely shrouded in shadows.
In a forest path, five human figures are desperately running, their rapid breathing and suppressed crying mixing together. Some of the moonlight spilling from the sky is obscured by dark clouds, and the five can only barely make out the path a few meters ahead.
On either side are dense bushes and various eerie, bare-branched trees, with the cold wind howling like the Devil's roar.
These five individuals consist of two men and three women: a curly-haired, glasses-wearing young man, a blond, muscular youth, a red-haired young girl, a middle-aged woman with short blond hair, and the oldest, a middle-aged woman with brown hair tied up, dressed in teacher's attire.
Because running in high heels is inconvenient, she has taken them off and is carrying them in her hand. Her fair feet have been cut by sharp stones and thorns, yet her stamina is second only to the strong young man among them.
